angular spectrum meaning in English
角频谱
角谱
Examples
- The results show that , as for the single - mode transmission , the dispersion relations yet include space - dispersion ( k dispersion ) which relates to angular spectrum of fields of in - waveguide , in addition to the material - dispersion and the waveguide - dispersion
分析结果表明：对于单模传输，色散关系中除了与频率有关的材料色散和波导色散外，还应包括与输入端光场的角谱有关的空间色散( k色散) 。 - A perturbation method by tight - binding approximation which provide the relation of phase constant and angular spectrum of fields of in - waveguide is presented . the strip width of phase constant can be given . on the other hand , the group delay - time due to the k dispersion in single - mode transmission can also be estimated
提出一种利用紧束缚近似的微扰法计算阵列波导的相位常数与输入光角谱的关系，由此算出相位常数的带宽，并利用衍射方法估算单模传输中k色散引起的群延时。
